EUROVAL Report Summary

Three dimensional boundary layer turbulence models

A limited range of turbulence models were tested by the use of boundary layer methods in the absence of numerical velocity. Of the turbulence models tested the Johnson-Coakley (JC) model showed the best performance for separating and separated flows whilst the Cebeci-Smith (CS) model remained the best for flows close to equilibrium.

For the calculation of separating and separated flows it was necessary to use an inverse method of calculation. This required extensive experimental data to be available and restricted comparisons to just one test case.
